The things network does not recognize the DevEUI of the NUCLEO-WL55JC1

[Salvatore5]

I tried to register an end-node on TTN, but it does not recognize the DevEUI.

I watched this video:

error:

I have entered the DevEUI here: (I copied the id that is on the board, tried several times but nothing)

Hello @Salvatore5 and welcome to ST Community

I suggest you to read the DevEUI address which is  defined from UID64 register and than use it to register your end-node on TTN. Also, make sure to follow all steps indicated in the video.

I hope this is helpful for you.

Issam.
